Marginal bone resorption (MBR) around osseointegrated dental implants is a multifactorial phenomenon that is not yet fully understood. The general consensus is that it is important to maintain stable bone levels and prevent excessive peri-implant bone loss. Implant design seems to play a critical role in influencing marginal bone remodelling.1 In this respect, the evaluation of implant neck configurations on marginal bone stability is of utmost importance, because the bone remodeling process is most dominant at this level.2,3 A close relationship was found between alveolar bone loss and the lengths of polished necks for various implant systems.4 Some studies claim that implants with shorter polished smooth collars are more effective in decreasing MBR in animal models.5 The same assumption has been confirmed in human studies evaluating the MBR around implants with different height configurations of the neck portion.6,7 However, scarce...
